Tiger Shark does not look for it it just snaps everything it sees floating. One fisherman caught this shark and found pants and underwear.
They also eat HUMANS!!!!!!
Excellent eyesight, acute sense of smell & an ability to pick up low-frequency pressure waves. They have strong jaws, serrated teeth & will take on large prey like other sharks (inc. fellow tiger sharks), sea turtles & dolphins. Along with fish, crustaceans, mollusks, seabirds & sea snakes, they will even attack an injured or ailing whale. With a reputation for eating anything & also because they aggressively swallow some prey whole, they mistakenly eat inedible objects, such as license plates, cans, tires & balls & are regarded as "the oceans garbage can".
